TECHNICAL FIELD
BACKGROUND
[0002] A spherical compressor is a newly invented variable-volume mechanism with a novel structure. The spherical compressor requires no intake/exhaust valve, few moving parts, and has the advantages of small vibration, high mechanical efficiency, reliable sealing performance, etc. There are many patents of spherical compressors, such as Chinese Patent No. 03114505.1 (titled "Variable-volume Mechanism for Compressor"), CN200610104569.8 (titled "Spherical Compressor Capable of Multi-stage Compression"), and CN201010264211.8 (titled "Hinge Sealing Automatic Compensation Mechanism for Spherical Compressor"). The application and development of spherical compressors have made steady progress in recent years. Spherical compressors can be widely used in various fields such as gas compressors, refrigerator and refrigeration air-conditioning compressors and pump machinery. Various power machines based on spherical compressors are undergoing industrialization.
[0003] Since the rotation of a piston of an existing spherical compressor is powered by an eccentric main shaft, when the main shaft rotates to the point where the axis of a turntable coincides with the axis of the piston, the resultant force of the main shaft acting on the turntable perpendicularly intersects with the axis of the piston and the axis of the turntable, so that the torque of the piston rotating around the axis of the piston is zero and the piston cannot rotate, thus causing clamping stagnation of the mechanism, which is the dead center of the mechanism. The Chinese Patent No. 201410100390.X titled "Anti-Locking Mechanism for Rotor of Spherical Compressor" aims to solve the problem of locking at a dead center of a spherical compressor. Specifically, a pin boss is added to a turntable shaft; a guide sleeve is arranged on the pin boss; a concave sliding chute is arranged on a base spherical surface of a cylinder body or a lower spherical surface of the cylinder body; and the concave sliding chute is distributed on the sliding track of the guide sleeve on the corresponding base spherical surface of the cylinder body or the lower spherical surface of the cylinder body during the rotation of a turntable. At the moment when the rotating torque of the turntable is zero, when the main shaft drives the turntable, the contact force generated by the guide sleeve and the concave sliding chute can still keep the turntable moving, so that the turntable is not prone to clamping stagnation, fundamentally solving the dead center problem during the movement of the spherical compressor mechanism. However, high precision of the concave sliding chute is required to ensure a good fit between the guide sleeve and the concave sliding chute, and a cooling mechanism is needed to prevent heat generation caused by friction of the guide sleeve and the concave sliding chute during the movement of the anti-locking mechanism, thus increasing manufacturing and operation costs. Chinese Patent Application No. 201310100697.5 discloses a mechanism synchronous with the rotation of a turntable in a spherical compressor, which can effectively overcome the problem that when the piston axis is coincident or approximately coincident with the turntable axis, the main shaft fails to drive the rotation of the piston. However, in this mechanism, the steel ball is required to be highly matched with the cross section of the concave sliding chute, and the abrasion will occur at the contact surface between the steel ball and the sliding chute.

As shown in Figs. 1-8, the spherical compressor includes a cylinder head 1, a cylinder body 2, a piston 3, a center pin 4 and a turntable 5. The cylinder body 2 and the cylinder head 1 have hemispherical inner cavities, and the cylinder body 2 and the cylinder head 1 are fixedly connected by screws to form a casing of the spherical compressor with a spherical inner cavity. An intake passage 103, an exhaust passage 104 and a piston shaft hole 105 are provided on the inner spherical surface of the cylinder head 1. The cylinder body 2 is provided with a turntable shaft hole 201 communicated with the outside of the cylinder body. One side of the turntable shaft hole 201 communicates with the spherical inner cavity, and the other side is provided with a bearing seat hole which is coaxial with the turntable shaft hole 201. The axis of the piston shaft hole 105 and the axis of the turntable shaft hole 201 both pass through the spherical center of the spherical inner cavity, and the included angle between the axis of the piston shaft hole 105 and the axis of the turntable shaft hole 201 is α. The intake passage 103 and the exhaust passage 104 on the cylinder head 1 are arranged in an annular space perpendicular to the axis of the piston shaft hole 105 on the inner spherical surface. An intake hole 101 and an exhaust hole 102 are further formed on the outer surface of the cylinder head 1. The intake hole 101 communicates with the intake passage 103, and the exhaust hole 102 communicates with the exhaust passage.
[0018] As shown in Figs. 9-12, the piston 3 has a spherical top surface, two side faces which form an angle and a piston pin boss at the lower part of the two side faces. The spherical top surface of the piston and the spherical inner cavity formed by the cylinder body 2 and the cylinder head 1 have the same spherical center and form a sealed loose fit. The piston pin boss is of a semi-cylindrical structure, and a piston pin hole 302 which penetrates is provided on the central axis of the semi-cylinder. The piston pin boss at the lower part of the piston 3 is provided with an opening so as to form a fan-shaped cavity on the piston pin boss of the piston 3. The opening of the piston 3 is located in the middle of the piston pin boss and perpendicular to the axis of the piston pin hole 302 of the piston pin boss, and the width of the opening of the piston 3 is matched with the width of the semi-cylinder of the turntable pin boss. The turntable 5 has a turntable pin boss corresponding to the piston pin boss, and the turntable pin boss is arranged at the upper part of the turntable 5. The outer peripheral surface between the upper part and the lower end face of the turntable 5 is a turntable spherical surface. The turntable spherical surface and the spherical inner cavity have the same center and is closely attached to each other to form a sealed loose fit. The two ends of the turntable pin boss are semi-cylindrical grooves, and the middle part of the turntable pin boss is a protruding semi-cylinder, and a turntable pin hole 502 which penetrates is formed at the center of the semi-cylinder. A turntable shaft 501 matched with the turntable shaft hole 201 on the cylinder body 2 is fixedly provided at the center of the lower end of the turntable 5, and a piston shaft 301 is fixedly provided with at the center of the spherical top surface of the piston 3. The turntable shaft 501 is inserted into the turntable shaft hole 201 on the cylinder body 2 to form a rotating pair with the cylinder body 2. The center pin 4 is inserted into a pin hole formed by matching the turntable pin boss with the piston pin boss to form a cylindrical hinge, and the matching surfaces of the cylindrical hinge form a sealed loose fit. The piston 3 and the turntable 5 form a sealed loose connection through the cylindrical hinge, and the two ends of the cylindrical hinge and the spherical inner cavity form a sealed loose fit.
[0019] The piston shaft hole 105 on the cylinder head 1 communicates with the spherical inner cavity of the cylinder head 1 through a via hole, and the radial dimension of the via hole is smaller than the diameter of the piston shaft hole 105. An annular positioning surface is formed at the lower end of the piston shaft hole 105. The piston shaft hole 105 on the cylinder head 1 is provided with a rotary sleeve 6 in a cylindrical shape which is placed in the piston shaft hole 105. The end face of the rotary sleeve 6 is attached to the annular positioning surface. The outer cylinder of the rotary sleeve 6 is coaxial with the piston shaft hole 105. The rotary sleeve 6 can rotate around the axis of the piston shaft hole 105. As shown in Fig. 9, a rotary sleeve sliding chute 601 which can slide in the direction of the axis of the center pin 4 is arranged on the end face of the rotary sleeve 6. The two side faces of the rotary sleeve sliding chute 601 serve as sliding working surfaces and are symmetrically arranged on both sides of a plane of the axis of the center pin 4 and the axis of the piston shaft hole 105 in the cylinder head 1. A piston shoe shaft hole 141 is provided at the center of the piston shoe 14. As shown in Fig. 10, the two side faces of the piston shoe 14 are parallel planes. A piston shaft pin hole 303 is provided at the end of the piston shaft 301, and a piston shoe pin hole 142 is formed in the corresponding position of the piston shoe 14. After the piston shaft 301 passes through the via hole through which the piston shaft hole 301 communicates with the spherical inner cavity, the end of the piston shaft 301 is inserted into the piston shoe shaft hole 141. A fixing pin 10 is inserted into a fixing pin hole formed by the piston shaft pin hole 303 and the piston shoe pin hole 142, and the piston shoe 14 is fixed to the end of the piston shaft 301 by the fixing pin 10. The two side faces of the piston shoe 14 are attached to the two side faces of the rotary sleeve sliding chute 601 respectively, and a loose fit is formed along the two side faces of the rotary sleeve sliding chute 601 in a sliding manner. The two side faces of the piston shoe 14 are parallel to the plane of the axis of the piston shaft hole 105 and the axis of the center pin 4. The rotary sleeve sliding chute 601 on the rotary sleeve 6 and the piston shoe 14 on the piston shaft 301 form a sliding chute swinging mechanism. The turntable shaft 501 is inserted into the turntable shaft hole 201 in the cylinder body 2 to form a rotating pair with the cylinder body 2. The turntable shaft 501 is driven to rotate such that the turntable 5 drives the piston 3 to move through the cylindrical hinge. The movement of the piston 3 is rotation around the axis of the piston shaft hole 105 and swings relative to the turntable 5 around the center pin 4. Meanwhile, the piston 3 swings along the two side faces of the rotary sleeve sliding chute 601 on the rotary sleeve 6 through the piston shoe 14 at the end of the piston shaft 301 relative to the axis of the piston shaft hole 301 on the cylinder head 1 with a swing amplitude of 2α. The length of the two side faces of the rotary sleeve sliding chute 601 in the direction of the axis of the center pin 4 should be long enough to ensure that the swing of the piston shoe 14 is not interfered. In this embodiment, the sliding chute swinging mechanism is used to provide the piston 3 with a degree of freedom to swing along the two side faces of the rotary sleeve sliding chute 601.
[0020] The piston 3 swings relative to the turntable 5 around the axis of the center pin 4, and a V1 working chamber 1001 and a V2 working chamber 1002 with alternatively variable volumes are formed between the upper end face of the turntable 5, the two side faces of the piston 3 and the spherical inner cavity. The intake passage 103 and the exhaust passage 104 on the cylinder head 1 are arranged in an annular space perpendicular to the axis of the piston shaft hole 105, and the intake passage 103 and the exhaust passage 104 communicate with an intake hole 101 and an exhaust hole 102 in the cylinder head 1 in communication with the outside of the cylinder body 2, respectively. The air intake and discharge control is realized by the rotation of the piston 3, and when the working chambers need to perform air discharge or air intake, the corresponding working chamber communicates with the intake passage 103 or the exhaust passage 104.
[0021] As shown in Fig. 3, in this embodiment, the turntable shaft 501 extends out of the cylinder body 2 and is connected to a power mechanism to serve as a power input end of the compressor. A sealing ring 7 is arranged on the inner side of the portion, engaged with the turntable shaft hole 201 on the cylinder body 2, of the turntable shaft 501, and a bearing 8 is arranged at the end of the engagement portion. The power mechanism drives the turntable shaft 501 to rotate, and the volumes of the V1 working chamber 1001 and the V2 working chamber 1002 change constantly and alternately. In Fig. 2, the V1 working chamber 1001 and the V2 working chamber 1002 are in the ultimate state. The V1 working chamber 1001 is in a state that the air intake of the spherical compressor has completed, so the theoretical volume of the V1 working chamber 1001 in the figure is maximum, and the V2 working chamber 1002 is in a state of starting the air intake of the next cycle after discharging the air, so the theoretical volume of the V2 working chamber 1002 in the figure is zero. Each time the turntable shaft 501 drives the turntable 5 to rotate by one cycle, the piston 3 rotates around the axis of the piston shaft hole 105 by one cycle, and at the same time, the piston 3 swings once along the two side faces of the rotary sleeve sliding chute 601 relative to the axis of the piston shaft hole 105 on the cylinder head 1 at a swing angle of 2α. Since the piston 3 swings once around the axis of the center pin 4 relative to the turntable 5, the V1 working chamber 1001 and the V2 working chamber 1002 undergo a complete intake or compression exhaust process, respectively.
[0022] A sealing plug 11 is provided at the end of the piston shaft hole 105 on the cylinder head 1, and an internal thread is provided on the inner hole in the outer end of the piston shaft hole 105. The sealing plug 11 is provided with an external thread matched with the internal thread, and the sealing plug 11 is arranged at the end of the piston shaft hole 105 by the threads in a blocking mode, so that compression media and lubricating oil cannot leak from the piston shaft hole 105.
[0023] In order to improve the manufacturability of the piston 3, as shown in Fig. 13, a piston insert 304 is arranged at the fan-shaped cavity at the opening of the piston 3. The piston insert 304 is matched with the opening of the piston 3 in size, and the top surface of the piston insert 304 is matched with the top surface of the opening of the piston 3. The two side faces of the piston insert 304 are matched with the two side faces of the piston 3. The two end faces of the piston insert 304 are matched with the two side faces of the opening of the piston 3. The lower end of the piston insert 304 is an arc of the same radius and coaxial with the piston pin hole 302 in the lower end of the piston 3. By making the top surface and the two end faces of the piston insert 304 and the top surface and the two side faces of the opening of the piston 3 into mutually matched planes, machining is convenient, and the machining precision and the matching precision after assembly are improved.
[0024] Inspired by this embodiment, those skilled in the art can perform the following deformation treatment on the turntable 5 and the cylinder body 2 without creative labor, and can also achieve the technical effect of the present invention: since the movement of the turntable 5 is rotation around the axis of the turntable shaft hole 201 on the cylinder body 2, the turntable spherical surface can be deformed into various forms of rotating surfaces around the axis of the turntable shaft hole 201 on the cylinder body 2, and the rotating surface can be spherical, cylindrical, conical and other forms. The inner spherical surface of the cylinder body 2 is also deformed into a rotating surface matched with the rotating surface of the turntable 5. The end faces of the two ends of the cylindrical hinge formed by the piston pin boss, the center pin 4 and the turntable pin boss and the inner surface of the cylinder body 2 are attached to each other and form a sealed loose fit during the movement of the piston 3 and the turntable 4. For this reason, the above-mentioned deformation scheme of the turntable and the cylinder body is also protected by this patent, and any technical scheme adopting the above-mentioned deformation treatment also falls within the scope of protection of the present invention.

The cylinder body 2 is provided with a turntable shaft hole 201 communicated with the outside of the cylinder body. The turntable shaft hole 201 in the cylinder body 2 communicates with the spherical inner cavity of the cylinder body 2 through a via hole, and the radial dimension of the via hole is smaller than the diameter of the turntable shaft hole 201.

The two ends of the turntable pin boss are semi-cylindrical grooves, and the middle part of the turntable pin boss is a protruding semi-cylinder. A turntable pin hole 502 which penetrates is formed at the center of the semi-cylinder. A turntable shaft 501 is provided at the lower end of the turntable 5, and a turntable shaft pin hole 503 is formed in the turntable shaft 501.

The center pin 4 is inserted into a pin hole formed by matching the turntable pin boss with the piston pin boss to form a cylindrical hinge, and the matching surfaces of the cylindrical hinge form a sealed loose fit. The piston 3 and the turntable 5 form a sealed loose connection through the cylindrical hinge, and the two ends of the cylindrical hinge and the spherical inner cavity form a sealed loose fit.
[0027] The lower end of the cylinder body 2 is connected to a main shaft 12 through a main shaft support 13, and the main shaft support 13 is fixedly connected to the lower end of the cylinder body 2 through screws to provide support for the rotation of the main shaft 12. The upper end of the main shaft 12 is placed in the turntable shaft hole 201. The outer cylinder at the upper end of the main shaft 12 is coaxial with the turntable shaft hole 201, and the main shaft 12 can rotate around the turntable shaft hole 201. A main shaft sliding chute 121 is provided on the upper end face of the main shaft 12 in the direction of the axis of the center pin 4, and the two side faces of the main shaft sliding chute 121 serve as sliding working surfaces and are symmetrically arranged on both sides of a plane of the axis of the turntable shaft hole 201 in the cylinder body 2 and the axis of the center pin 4. Similar to the structure of the piston shoe 14 in the first embodiment, a piston shoe shaft hole 141 is provided at the center of the piston shoe 14. As shown in Figs. 10, 15, 16 and 18, the two side faces of the piston shoe 14 are parallel planes. A turntable shaft pin hole 503 is provided at the end of the turntable shaft 501, and a piston shoe pin hole 142 is formed in the corresponding position of the piston shoe 14. After the turntable shaft 501 passes through the via hole through which the turntable shaft hole 201 communicates with the spherical inner cavity, the end of the turntable shaft 501 is inserted into the piston shoe shaft hole 141. A fixing pin 10 is inserted into a fixing pin hole formed by the turntable shaft pin hole 503 and the piston shoe pin hole 142, and the piston shoe 14 is fixed to the end of the turntable shaft 501 by the fixing pin 10. The piston shoe 14 is arranged in the main shaft sliding chute 121 in the end of the main shaft 12, and the two side faces of the piston shoe 14 are attached to the two side faces of the main shaft sliding chute 121 and slide along the two side faces of the main shaft sliding chute 121 to form a loose fit, and the main shaft sliding chute 121 on the main shaft 12 and the piston shoe 14 on the turntable shaft 501 form a sliding chute swinging mechanism.
[0028] The lower end of the main shaft 12 extends out of a shaft hole of the main shaft support 13 and is connected to a power mechanism. The main shaft 12 drives the turntable shaft 501 to rotate through the two side faces of the main shaft sliding chute 121. The turntable 5 drives the piston 3 to move through the cylindrical hinge. The movement of the piston 3 is rotation around the axis of the piston shaft hole 105. The movement of the turntable 5 is rotation around the axis of the turntable shaft hole 201 and swings around the center pin 4 relative to the piston 3. Meanwhile, the turntable 5 swings along the two side faces of the main shaft sliding chute 121 through the piston shoe 14 relative to the axis of the turntable shaft hole 201 in the cylinder body 2 at a swing angle of 2α. The length of the two side faces of the main shaft sliding chute 121 in the direction of the axis of the center pin 4 should be long enough to ensure that the swing of the piston shoe 14 is not interfered. In this embodiment, the sliding chute swinging mechanism is used to provide the turntable 5 with a degree of freedom to swing along the two side faces of the main shaft sliding chute 121.
[0029] The turntable 5 swings around the center pin 4 relative to the piston 3, and a V1 working chamber 1001 and a V2 working chamber 1002 with alternatively variable volumes are formed between the upper end face of the turntable 5, the two side faces of the piston 3 and the spherical inner cavity. The intake passage 103 and the exhaust passage 104 on the cylinder head 1 are arranged in an annular space perpendicular to the axis of the piston shaft hole 105. The intake passage 103 and the exhaust passage 104 communicate with an intake hole 101 and an exhaust hole 102 in the cylinder head 1 in communication with the outside of the cylinder body 2, respectively. The air intake and discharge control is realized by the rotation of the piston 3, and when the working chambers need to perform air discharge or air intake, the corresponding working chamber communicates with the intake passage 103 or the exhaust passage 104.
[0030] The power mechanism drives the main shaft 12 to rotate, and the main shaft 12 drives the turntable shaft 501 to rotate through the two side faces of the main shaft sliding chute 121. The volumes of the V1 working chamber 1001 and the V2 working chamber 1002 change constantly. In Fig. 15, the V1 working chamber 1001 and the V2 working chamber 1002 are in the ultimate state, the V1 working chamber 1001 is in a state that the air intake of the spherical compressor has completed, so the theoretical volume of the V1 working chamber 1001 in the figure is maximum, and the V2 working chamber 1002 is in a state of starting the air intake of the next cycle after discharging the air, so the theoretical volume of the V2 working chamber 1002 in the figure is zero. Each time the turntable shaft 501 drives the turntable 5 to rotate by one cycle, the piston 3 rotates around the axis of the piston shaft hole 105 by one cycle, and at the same time, the turntable 5 swings once along the two side faces of the main shaft sliding chute 121 relative to the axis of the turntable shaft hole 201 on the cylinder body 2 at a swing angle of 2α. Since the turntable 5 swings once around the axis of the center pin 4 relative to the piston 3, the V1 working chamber 1001 and the V2 working chamber 1002 undergo a complete intake or compression exhaust process, respectively.

[0033] In order to improve the manufacturability of the piston 3, as shown in Fig. 14, a piston insert 304 is arranged at the fan-shaped cavity at the opening of the piston 3. The piston insert 304 is matched with the opening of the piston 3 in size, and the top surface of the piston insert 304 is matched with the top surface of the opening of the piston 3. The two side faces of the piston insert 304 are matched with the two side faces of the piston 3. The two end faces of the piston insert 304 are matched with the two side faces of the opening of the piston 3. The lower end of the piston insert 304 is an arc of the same radius and coaxial with the piston pin hole 302 in the lower end of the piston 3.
